Problem installing touchpad driver

[Fabrice]

Well;

I did some testing with the MS Natural keyboard Pro and Logitech USB Mouse, after I uninstalled the drivers from both hardwares:

MS IntelliType Pro and Mouseware 8.60

My computer did not find the touchpad at reboot, I had to add the touchpad manually with add hardware

I tried to install the newer driver 5.0.45

and got these errors:

Enum/Bios/*PNP0F13\13
SUReg Createkey failed

and

Severe: a serious internal error has occurred please contact your touchpad supplier


and in device manager, I have under mouse:

PS/2 compatible mouse port (with exclamation mark)

Synaptics PS/2 Touchpad

the thouchpad seems to work normally but I am sure the installation did not go well, I am not sure about the PS/2 Compatible mouse port entry, I have no mouse connected to laptop.

If I try to remove that entry, the cursor freeze and no mouse ability at all, and it redetects it after the restart.

what should I check?
any guidance?

Thanks for any inputs

I have a Dell Inspiron 7000 with Synaptics touchpad

Old thread but the problem lives on. Caused me so much frustration I'm looking for a place to plant this info so people can google it and find it.

First
Bootup into safe mode and try the install from there.


Failing that,
Update the BIOS and boot into safe mode and try installing again


Failing that,

1. Log on to the computer by using an account that has administrative credentials.
2. Click Start, click Run, type regedit in the Open box, and then click OK.
3. Locate the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ENUM\PCI
4. Right-click the subkey that is related to the device that is experiencing the symptom, and then click Permissions.
5. Click Advanced, and then click the Permissions tab.
6. Make sure that the following default permissions are configured:
* Everyone: Read
* System: Full Control
7. Click to select the Replace permission entries on all child objects with entries shown here that apply to child objects check box, and then click Apply.
8. Click Yes, and then click OK two times.
9. Quit Registry Editor.
10. If the issue is not resolved, repeat this procedure, and grant full control permissions to the Everyone group on this subkey.

Repeat with registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ENUM\
# Right-click PCI, and then click Permissions.

Wow---well, I tried all of your suggestions, and NOTHING worked! But, I realized that since this problem clearly had something to do with the registry, the easiest fix might be XP's System Restore...so, I went back to the day before the problem started, and sure enough, BAM! All better now...So sad that I wasted 2 hours on this, before that occurred to me! LOL
